I received these messages when first putting my prepaid sim card into the iphone. I was new at this and was wondering why they were charging me for doing nothing. These charges stem from data access. Even though one doesn't have a data access package, you can see from the settings > usage > EDGE Net work Data under Sent and Received that KB is still increasing everytime you open safari or perform any data access activity. It doesn't matter if a web page loads all the way or not. For some reason, you still are downloading something in the process.
What you need to do is truly disable EDGE Networking. USE THE LINK below for COMPLETE instructions:
access the file:
/var/root/Library/Preferences/com.apple.carrier.plist
and edit the settings within the file using WinSCP or any other SSH program with text editing capabilities. I don't think it works with "TextEdit" iPhone app though. You have to save the changes you make in the file through your computer. Remember to reboot after you save the changes. Seems to be working fine for me.
